Lighting the Way with Freeform Optics

In a recent paper in Light: Science & Applications, University of Rochester researchers Jannick Rolland and Jacob Reimers describe an optical device with potential applications ranging from improved satellite and diagnostic imagery to more precisely matching the paint color on a living room wall. The new device employs the revolutionary idea of “freeform optics” to compensate for difficulties that arise in trying to put optics in small packages.
